My pleasure Mary, I agree with you that we as NCUC need to start covering the whole spectrum of ICANN activities and try to take advantage of the vast expertise we all can contribute to the process. As a related comment to the root scaling studies, you also need to take in account that so far all the studies are focusing on the root zone and not on the DNS as an integral system. There are major implications that all these changes are already manifesting on the client side. I'm in permanent contact with a great friend and colleague also member of NCUC from the University of La Plata in Argentina (Eduardo Suarez) who has been performing many tests on a real and running network at the Faculty of Astronomic Sciences. Given that DNS is not only used for simple name resolution, it's also being used to manage email routing, consult many different spam blocking services that use DNS as the foundation for it, and other stuff like geo location, etc, the increased load on a local client or small server grows dramatically when not only the server has to dedicate more memory and CPU because of the increased number of threads handling TCP connections, with DNSSEC you also require many more CPU cycles to digest and process the DNSSEC responses. As far as I know, no studies have been included yet in the ICANN process to have a better understanding of the entire system, there some inferences but not actual work done on the field and particularly in places where connectivity or computing resources are limited.
